1 Claim.

This invention relates to new and useful improvements in cultivatorattachments especially adapted for power-driver tractors.

The principal object of the present invention is to provide a cultivatorattachment for the front I axles of present types of Ford tractors. I

Another important object of the invention to provide a cultivatorattachment of the character stated which will at all times be clearlyvisible to the operator of the tractor. I l

Another important object of the invention is to provide a frontcultivator which can be controlled in response to the controlledposition of arear cultivator.

Other objects and advantages of the invention will become apparent tothe reader of the following specification.

Inthe drawings: 1

Figure 1 represents a top planview of a tractor shown equipped with thepresent invention.

Figure 2 is a side elevational view of a tractor with the presentinvention installed thereon.

Figure 3 is a front elevational'view of a tractor showing the presentinvention.

Figure 4 is a perspective view showing one of the side units of vtheinvention.

Referring ..to the drawings wherein like numerals designate like parts,it can be seen that numeral 5 generally refers to a conventional Fordtractor which has the usual steering wheel 6, seat I and plant 8 orsupplying power to the rear wheels 9, 9. i I

This type of tractor has an axle ill equipped at its ends with steeringwheels II.

In carrying out the present invention, at each side of the power plant 8and secured to an end portion of the axle ili is' a unit generally re-.

ferred to by numeral i2 of the present invention.

Each of these units consists of an elongated tapered block l3 which goesagainst the forward side of the axle l0 and is tapered so as to make upfor the diverged relationship of the end portions of the axle l0, thatis, so that the forward sides of the blocks ii are substantially alignedwith each other.

Each of these blocks l3 has rearwardly extending and threaded members llwhich extend through openings in the axle l0 and are equipped with nutsl5. Ears i6, i6 extend forwardly from the blocks i3 and have endportions of a shaft l1 journaled therethrough. An arm l8 rises from theshaft I] and is pivotally connected as at I 9 to the forward end of arod 20 which extends from a conventional cultivator mechanism generallyreferred to by numeral 2| (see 8ure 1).

Collars 22, 22 are located on the shaft l1 and as is shown in Figure 4,the shaft H has a plur-ality of longitudinally spaced and 'threadedopenings 23 for receiving adjusting screws 24 on the collars 22, thatis, to the end that the collars can be adjusted to various points on theshaft ll.

Elongated square bars 25 have their forward ends disposed upwardly as at26 and are formed to be welded or otherwise joined with the collars 22.

Blocks 2! are slidably disposed on the squared bars 25 and are held inplace by set screws or the like 28. Cultivator shovels 29 provided withupstanding shanks 30 have these shanks vertically disposed andadjustable through the blocks 21.

. It can be seen that the rods 20 extend to the rear cultivatormechanism'2l so that whenever the rear cultivator mechanism is lifted,the front units l2 are likewise lifted to the end that the tractor cantravel over paved streets.

, By having the cultivator attachment -thus mounted on the front axles,the wheels act as gauge wheels allowing the shovels to follow the groundregardless of its unevenness. This particular mounting of the cultivatorattachment allows for quick action in dodging staggered corn, etc.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A cultivator attachment for the front axles of tractors comprising ablock having forwardly extending cars, a shaft disposed between theears, a collar adjustable on the shaft, a bar extending from the collar.and an adjustable cultivator element carried by the bar.
